In this world, humans, elves, goblins, and other unique living beings live. And like all societies, classes define stereotypes, thus bringing discrimination. Diluc, the prince of Mondstadt decides to go on a lonely quest to find the mythical blood crystal (a powerful source that could wipe out humanity if placed in the wrong hands).

As he rides his horse through the forest towards Liyue, he hears rustling in the bushes. He immediately unsheathes his claymore, waiting for a possible ambush.
